MILKING-MACHINE.

Be it known that I, ARTHUR NIHLEN, a l citizen of the United States, residing at .Tow York city, in the county of N W,.York, State of New York, have invente certain and useful Improvements in Milking- Machines; and I do hereby declare thej'ollow-ing to be a full, clear, and exact descrip-f others skilled in the art to which it a.pper' tains to makeV and use the same. l 1

This invention relates xto milking machines and especially to that class in which themilk is drawn 'ti-om -the udder by an intermittent pressure exerted upon the teats. y The object of the invention is the lproduction of a machine of thetype named which will perform a given amount. of work in less time than it can be accomplished manuallyV and which will the same time be naturalV in its effect and non-injurious to the animal. .A further-object of the invention is the construction of amaehine of the. class indicated which will beexceedingly simple7 efective in use and Acomparatively inexpensive' to manufacture, install. Aand maintain.

With the above and other objects in view the invention consists in the details of construction and in the combination and ar- Slieceation of Letters Patent. Application niedfzanuary 22, i910.

other sections 10 and 11,.

The sections 8V secured lo one lapping tongues 12 and 13 respectively; said' be capable of tongues being oiiset from the main bod'y porti ,body iortions Will'be positioned in the saine vertical plane.

The tongues 12 and 1B are each provided withregistering. slots through inserted; 'said slots being y of sutlicient Alength to permit a limited more4- I vwhich a bolt 14 is nient of the sections toward and away from each other and the bolt serving to lock said sections' in a `desired adjusted relation.

Likewise the sections 10 and llare provided offset oVerp, 'respectively'. said at i their adjacent edges with lapping tongues 1.5 and 16 tongues being provided with registering circular apertures for the-.reception of'a bolt 1.7. said apertures being and 11 are non-adjustably secured together.

Journaled inthe section 10 and projecting externally'of said section a shaft '18 which carries at its outer end a bcif'el gear 19. while an ordinary gear 20 is mounted on saidshaft and the outer tace.

between the bevel gear 19 of the section 10. A5 corresponding shaft 1S is journaled in the that will be presentlyapparent. `Secured to the outer face of the section 10 is a bracket 91 which has a shaft 22 joiirnaled therein. Said shaft. 22 carries on one end a. bevel 23 in mesh l other en d a plurality of pulleys 24. of varying diameters. A pair of .tracks 25 and 26 Vprovided :it their upper ends with inwardly substantially the saine diameter as bolt 17 whereby thesections 10` y v80 section 8 for :i purpose' gear with the bevel gear 1)y and on its nf ofvsaid sections so that said main extendin 'flanees 27. have their loiverends pivoted respectivel'iY to the sha fts 18 and 18 and are disposed adjacent the inner face 'of N the sections 8 and 10 respectively. VThe upper ends oi the tracks 25 and 26 have, journaled therein a shaft 28, thel terminals of which project througl-iarcuateslots QQ-aiid 30 in `the sections 8 slots beingthe arc eta circle Whose center is the longitudinal 18, and Whose radiusis the. distance shafts 18 and 1.8 and shaft 28. upon the shaft 28 inward' ofthe 'and '26 respectively areprocket e Passngfthroiigh the track 26 intermediat its ends and hiivinf;r a journal bearing therein is a short shaft 31 which Mounted axisof the shafts 18.*. and.

tracks 2.5 i

projects at one end through an arcuate slot 32 in the section 1 0; ysaid slot being'concentric with thc varcuate slot 30. Mounted on the outer end of this short shaft 31 is a ear Wheel 33 while the inner end ot said s aft 'carries a sprocket wheel 34 disposed in vertical alinement with the sprocket wheel BO.

Passing through ,the track 26 between shafts 31 and 18 and having' a journal bearing in said track is another short shaft 35 which projects through an arcuate slot 36 vin the y spect to shaft 18 and journaled in section 10 is a shaft 38 which has mounted thereon a,

gear 39 in mesh with gear 20.

Journaled in the track and having its outer end projecting into an arcuate slot40, concentric with the slot 29 is a short shaft 41 the inner end ofwhich has mounted thereon a sprocket Wheel '42 in .vertical alinement with the sprocket'wheel 29.

Traveling upon the sprocket wheels 30' and 34 is a sprocket chain 40 and asimilar chain 4 1 is mounted `tor travel upon sprocket wheels 29 and 42. Connecting the chains 40 land 41 at suitable intervals are the presser rollers'43 which are constructed preferably of rubber so as to yield gently under pressure. The rollers. 43. as is 'usual have their vcores ormedfof a nonereslient material which in this ,instan'ce areextended at each end as. at 114 and serve the double function of securing the rollers-to the sprocket chains and of constituting a. Apivot pin for connecting ,certain adjacent links-of the sprocket' chains together. During the travel of the chains 40 and ,41"they pass over the inwardly extenfding flanges 27 of the tracks and 26. f i

ln order to ,constantly tend to hold the tracks 25 and 26 and the shaft 28 at the.

forward end of the, slots`29 and 30 there is mounted on each ofthe sections 8 and '10 cmresponding4` spring actuated devices eX- crting a force on the terminalsof said shaft 28 to move same toward the nnerend of said slots 29 and B0. 'Aseach of these devices are identical iue'very respect only that which is mounted on the section 10 will be referred to in detail. Saiddevice comprises a tubular 'member 45 which has one end` thereof closed by a filling of lead 46 and projecting through the wall. of said tubular member and having one end thereof embedded in the filling 46 is a setscrew 47. The outer end ofsaid set screw is' ,threadedand pryided with a tliiunb'nut 48s VThe'tube 45 issflotted longitudinally as' at 49 to receive the' track 25 and a spiing 50 is mounted in said ltube and has one" rid bearing against the track 26- and the other end Abearlng against the filling 46. The tube has secured to and dependingtherefrom va metal plate 51 adapted to bear a ainst the outer face of the section l0 when t e device is mounted thereon. Said deviceis adjustably secured to the section 1() by'slott-in'g said section vertically as at 52 and projecting the set screw 47 through said slot so that the threaded end thereof will be disposed beyond the outer face of said section. The nut 48 is then mounted on the screw 47 and it will be readily seen that the the limits of the-slot 52 and thus moved away from and toward the pivot point of the' track 26 and secured in any vdesired position. It will thus be ap arent that when the track 26 is inserted int e slot 49 the spring 50 will Constantl'ytid to force said track and shaft 28 tdward the inner end of the slot 29 but will permit said track and shaftto be moved toward the outer end of said slot when a pressure greater than the spring 50 is eX- ertedon the rollers 43. The force exerted by the spring 45 can be .increased by adjusting the device away from the pivotof the track 26 and decreased by an adjustment of the device in the opposite direction.

Connecting the inner edges of the sections 8 and 10 is a vertically disposed presser plate which has its upper end curved toward the center of the machine in the form of a circle as at 61.

Journaled'in the sections 9 and 1 1 and disposed therebetween is a shaft 'which has mounted thereon externallyoi the section 11 a gear wheel 54, saidsliaTt 53 -being disposedfin horizontal alinementwith the shafts 18 and 38 journaledin the section 10. Another short shaft 55 is jonrnaled. in the section 11. and disposed between the 'shafts 38 and 53 in horiffpntal 'alineincnt therewith and has mounte 3 thereon externally of Ythc section 11 a gaat Wheel '56 which meshes with the gear 3 9 andthe gear wheel 54..

Itv will be understoodthat the shaft 53 and the gear Wheel 54 correspond Withfjghe shaft- 18 and the gear Wheel 20 mounted" etween the sections 8 and 10 and as'the parteV of the machine which are disposed above p the shaft 53 and gearwheel ,54 .between the sections 9 and 11 are identical with those dis osed above the shaft 18V-and gearwvheel- 20 etween lthe sections 8 and, 16a detail dc- `scription thereof will be omitted'. v

As has been previously mentioned the sections 8. and 9.are adapted to be adjusted to device just described can be adjusted within I ward andaway from each other and in order to secure said sections a desired ad justed ppsition a latch'57 is pivoted to the A section'Qland-has provided on its lower edge series of teeth, 58 which are adapted to inn Aterlock with a pin 59 secured to the section 8. I l'n operation, a "air of teats are placed between each Set o rollers 43 and their accompanyingplates 60. The shaft 22 is thenrotatctl by a hclt connct'tion hctwccn inillcys Q4 anti a suitahlc poum' shaft.
